Abstract (en)
A transition metal complex of the following formula (1): in which A represents an atom of Group 16 of the periodic table; B 1 represents an atom of Group 14 of the periodic table; M 1 represents a transition metal atom of Group 4 of the periodic table; Cp 1 represents a group having a cyclopentadiene anion backbone; R 1 , R 2 , R 3 , R 4 , R 5 and R 6 represent independently of one another a hydrogen atom, a halogen atom, a C 1-20 alkyl group optionally substituted with a halogen atom; R 7 , R 8 R 9 , R 10 , R 11 and R 12 represent independently of one another a hydrogen atom, a C 1-20 alkyl group optionally substituted with a halogen atom; and a 1,3-diene comprising R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and 4 carbon atoms coordinates on M 1 , and the 1,3-diene may be of either a cis or trans form, or a mixed form thereof, although the coordination form is not limited, and the double bonds may be delocalized. When this transition metal complex is used as a catalytic component, high molecular weight polyolefin is produced with high catalytic activity.
